Rails - Mar 2006 - Dynamic Finders with _or_create Don''t Work?

What could cause this?
>>  sdfl=PartNumber.find_by_part_number("1111111")
=> #<PartNumber:0xb78fc744
@attributes={"id"=>"11601",
"part_number"=>"1111111"}>
>>  sdfl=PartNumber.find_or_create_by_part_number("1111111")
NoMethodError: undefined method `find_or_create_by_part_number'' for
PartNumber:Class
        from
/usr/lib/ruby/gems/1.8/gems/activerecord-1.12.2/lib/active_record/base.rb:942:in
`method_missing''
        from (irb):5

I could swear this used to work.

Anyone?  This is kinda disturbing to me.  Am I the only person who has 
ever seen this?  If the find_by works, shouldn''t the find_or_create_by 
also at least try to work?  My setup is plain vanilla.  PartNumber only 
has one attribute, part_number besides the id.
